Block Id

There should be a number, digitally etched onto a pad down along the pad rail, I believe on the pass. side of the block. A long time ago, I was able to track that number I found on a block to the fact it came from a truck. This was back in about 04-05 and I can't even begin to remember how I went about tracking it. Isa ***** gettin' old.

Look for that number, if not the one you already have, and find a good Chrysler parts counterman. I'll be he could help tell you what it's from. For that matter, why do you need to know? It's either a variable cam block (09 up) or not variable cam (08 down). Other than that, they're the same between the cars and trucks...
